As the world progresses towards a greener future, United Chemicals is playing its part in providing sustainable solutions to the industry. We have spent several years focusing on the the production of environmentally friendly, VOC-free, Zero Discharge of Hazardous Chemicals (ZDHC) Manufacturing Restricted Substances List (MRSL) compliant and REACH-compliant products. wanted to offer our customers more sustainable products. In an attempt to reduce the environmental impact of leather, United Chemicals developed a new range of polymers for leather.

New Generation in Wet-End

The polymer range yields high-end leathers for garment, upholstery, footwear and double-face articles. These polymers enable tanneries to leave less of a mark on the environment and make their end products more sustainable. By using fewer chemicals, the tanneries can get more from their process. United Chemicals promotes this chemical range as FOSMASOL, or ‘For Smart Solutions’. Those solutions include Polysol, ProWhite, Polysoft and Polytan – chemicals that are extremely versatile and adaptable for the needs of the tanneries.

Doing Less With More

The Polysol range includes polymer-based degreasing and wetting chemicals, increasing the waste water quality of the tanneries since they are VOC-free and natural chemicals.

For the tanning process, United Chemicals offers ProWhite. This novel tanning system can be used in both chrome-free tanning and metal-free tanning systems. ProWhite can be used without the need for the pickling process, thus leathers tanned with ProWhite
do not need salts and have lower acid consumption. Compared with regular tanning operations, ProWhite Tan yields a simple process method, and reduces the time and energy required for tanning.

In the fatliquoring process, Polysoft polymers give fuller and elastic leathers due to their increased molecular weight. Thanks to the chemical structure of Polysoft chemicals, the fatliquoring process yields lighter leathers and higher mechanical properties. Polysoft products also help to give a more homogenous dyeing and retanning effect.

As for the retanning, Polytan gives fuller and elastic leathers. The chemicals of the Polytan range are highly ecological, do not include salts, and have lower biological oxygen and chemical oxygen demand. In addition to being environmentally friendly, the polymer range increases the organoleptic quality and the mechanical properties of the articles produced.

ZDHC MRSL Compliant – and more

We encourage our customers to take this step towards the future and share our vision on reducing the environmental impacts of chemicals and a transparent supply chain. Tanneries can help to form a more transparent supply chain by assisting in fulfilling the ZDHC 2020 goals.

If you want to be a part of this future, a technical team is always more than willing to help you during this transformation.
